Description
Technical field
The present invention relates to a kind of DC-DC converter of carrying out boost action, particularly relate to a kind of shape of the iron core used in transformer.
Background technology
Fig. 1 is the circuit structure diagram representing relevant DC-DC converter.Fig. 2 is the equivalent circuit figure of the coupling transformer 20 in the relevant DC-DC converter shown in Fig. 1.DC-DC converter shown in Fig. 1 has DC power supply Vi, coupling transformer 20, switch Tr1, Tr2, diode D1, D2, filtering capacitor Co, load resistance Ro and control circuit 100.
As shown in Figure 2, coupling transformer 20 has transformer T3, transformer T4 and reactor L3.Transformer T3 has: primary winding 105a (number of turn np), the winding coil 105b (number of turn np1) be connected in series with primary winding 105a, secondary coil 105c (number of turn ns) with primary winding 105a and the coil 105b electromagnetic coupled that reels.Transformer T4 is formed in the same manner as transformer T3, has: primary winding 106a (number of turn np), the winding coil 106b (number of turn np1) be connected in series with primary winding 106a, secondary coil 106c (number of turn ns) with primary winding 106a and the coil 106b electromagnetic coupled that reels.
Primary winding 105a at the two ends of DC power supply Vi via transformer T3 is connected between the collector electrode-emitter of the switch Tr1 be made up of IGBT (igbt).Primary winding 106a at the two ends of DC power supply Vi via transformer T4 is connected between the collector electrode-emitter of the switch Tr2 be made up of IGBT.The primary winding 105a of transformer T3 and the tie point of the collector electrode of switch Tr1 and the emitter of switch Tr1 are connected with the series circuit be made up of winding coil 105b, diode D1 and the filtering capacitor Co of transformer T3.The primary winding 106a of transformer T4 and the tie point of the collector electrode of switch Tr2 and the emitter of switch Tr2 are connected with the series circuit be made up of winding coil 106b, diode D2 and the filtering capacitor Co of transformer T4.
Reactor L3 is connected with at the two ends of the series circuit of the secondary coil 105c of transformer T3 and the secondary coil 106c of transformer T4.Control circuit 100 controls according to the output voltage Vo of filtering capacitor Co, connects to disconnect preceding switch Tr2 to switch Tr1 after switch Tr1 connects, and disconnects preceding switch Tr1 connect at switch Tr2.That is, carry out following control: switch Tr1 and switch Tr2 is alternatively connected, and during predetermined repetition, make switch Tr1 and switch Tr2 connect in each 1/2 cycle simultaneously.
The relevant DC-DC converter of formation like this makes switch Tr1 connect according to the control signal Tr1g from control circuit 100, after during predetermined repetition, when switch Tr2 being disconnected according to the control signal Tr2g from control circuit 100, electric current is along Vi (+side), 105a, Tr1, Vi (-side) flowing, and therefore the electric current of switch Tr1 increases linearly.Meanwhile, also produce voltage at the secondary coil 105c of transformer T3, electric current L3i flows through by the clockwise path along 105c, L3,106c, 105c.
Electric current L3i flows through according to the law of equal ampereturns of transformer, puts aside energy, and also flow through identical electric current at reactor L3 in the secondary coil 106c of transformer T4.Therefore, the voltage that induction is corresponding with the number of turn in the primary winding 106a and winding coil 106b of transformer T4.
In addition, when the winding of transformer T4 ratio is set as A=(np+np1)/np, in diode D2, the electric current of the 1/A of the electric current of switch Tr1 flows through along Vi+, 106a, 106b, D2, Co, Vi-.Until the moment of turn on-switch Tr2 flow through the electric current of diode D2.The output voltage Vo of filtering capacitor Co is the voltage (input voltage) of DC power supply Vi, the voltage produced at the primary winding 106a of transformer T4 and the voltage sum produced at the winding coil 106b of transformer T4.
When the duty ratio (D=Ton/T) of switch Tr1 is set to D, the voltage produced in transformer T4 is AViD.Ton is the turn-on time of switch Tr1.T is the cycle making switch Tr1 carry out switch.The output voltage Vo of filtering capacitor Co becomes Vo=Vi (1+AD), can control output voltage Vo by changing duty ratio D.
Then, when making switch Tr2 connect according to the control signal Tr2g from control circuit 100, after during predetermined repetition, when switch Tr1 being disconnected according to the control signal Tr1g from control circuit 100, electric current is along Vi+, 106a, Tr2, Vi-flowing, and therefore the electric current of switch Tr2 increases linearly.Meanwhile, also produce voltage at the secondary coil 106c of transformer T4, electric current L3i increases simultaneously according to the path flowing through 106c, 105c, L3,106c clockwise.
Electric current L3i flows through according to the law of equal ampereturns of transformer, puts aside energy, and flow through identical electric current at reactor L3 in the secondary coil 105c of transformer T3.Therefore, the voltage that induction is corresponding with the number of turn in the primary winding 105a and winding coil 105b of transformer T3.
In addition, when the winding of transformer T3 ratio is set as A=(np+np1)/np, in diode D1, the electric current of the 1/A of the electric current of switch Tr2 flows through along Vi+, 105a, 105b, D1, Co, Vi-.Until the moment of turn on-switch Tr1 flow through the electric current of diode D1.The output voltage Vo of filtering capacitor Co is the voltage (input voltage) of DC power supply Vi, the voltage produced at the primary winding 105a of transformer T3 and transformer T3 the voltage sum that produces of winding coil 105b.When the duty ratio (D=Ton/T) of switch Tr2 is set to D, the voltage produced at transformer T3 is AViD.Ton is the turn-on time of switch Tr2.T is the cycle making switch Tr2 carry out switch.The output voltage Vo of filtering capacitor Co becomes Vo=Vi (1+AD), can control output voltage Vo by changing duty ratio D.
